SEAT-BACK.

To all whom it may concern:

Be it known that I, HOWARD G. Bnor'r.

-a citizenv of the United States, residing at Portland, in the county ofMultnomah and State of Oregon, have invented a new and useful Seat-Back,of which the following is a specification.

This invention relates to backs for board seats such as used incircuses, baseball parks and other places of assembly, one of theobjects of the invention being to provide a back which can be readilyapplied to or removed from the seat without requiring the use of anyseparate fastening means, the entire back being formed in a singlelength of spring material whereby a yielding support for the back of theuser is obtained.

ith the foregoing and other objects view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed, without departing from the spirit of theinvention.

In the accompanying drawings the preferred form of the invention hasbeen shown.

In said drawings :Figure 1 is a perspective view of the back, the seatto which it is applied being indicated by dotted lines. Fig. 2 is anenlarged section on line A-B Fig. 1.

Referring to the figures by characters of reference 1 designates a sidestrip of the back, said strip being provided, at its lower end, with aforwardly extending U-shaped clip 2 occupying substantially the sameplane as the strip 1. The upper end of this strip 1 merges into a crossrod 3 having a downwardly extending terminal arm t provided at its freeend with a forwardly extending eye5, there being a coil (3 upon the arm1 and above and close to the eye 5, this coil being formed by the end ofthe wire of which the arm 1 and the eye 5 are made. Another side strip 7is provided and is similar to the strip 1, said side strip having, at

its lower end, a forwardly extending U- shaped clip 8 similar to theclip 2, the lower terminals of the two clips 2 and 8 being constrip 9.At its upper end the side strip 7 merges into a cross rod 10, this rodextending between the Specification of Letters Patent.

eye 5 and the coil 6 and the upper portion of the side strip 7 beingseated within the eye. Thus it will be seen that the angle formed by therod 10 and strip 7 is'held against movement relative to the arm 4 aswill be apparent by referring especially to Fig. 2. That end portion ofthe rod 10 farthest removed from strip 7 is coiled around the upperportion of the side strip 1 and the portion of the top rod 3. Thisadjacent coil, which has been indicated at 11, thus serves to secure therod 10 to the side strip 1 and, by engaging the top rod 3, serves toprevent the rod 10 from sliding upwardly or downwardly along the sidestrip 1.

From the foregoing it will be seen that the entire back is formed in asinglelength of material, this material being preferably in the form ofa stiff spring wire of sufficient strength to properly support the backof an ordinary person.

In using the back, the clips 2 and 8 are placed in engagement with thefront edge portion of the board seat C and are then pushed rearwardlyonto the board until the side strips 1 and 7 are brought close to therear edge of the board. The person using the back can then be seated onboard C between the clips 2 and 8 and the upper and lower cross rods 3and 10 will extend across the back and constitute eflicient supports.-

It will be apparent that a seat back such as herein described can becheaply manufactured and as it is formed in but a single length of stiffWire, there are no parts which can get out of order.

The device is moved from position on the board seat C without the use ofscrews, clamps or any other similar devices such as have heretofore beennecessary in applying backs to seats of this type.

If desired a cushion may be combined with the seat. This cushion, whichhas been indicated at 12 may be of any preferred construction and ispreferably formed with eyes- 13 at the back corners thereof and whichslidably engage the side strips 1 and 7.

As the side strips land 7 diverge upwardly it will be seen that, shouldit be desired to clean the board on which the cushion l2 r'ests, it ismerely necessary to swing the cushion upwardly and back- 5 wardly so asto cause it to pass between the 1 side strips 1 and 7 whereupon it Wlllhang particularly advantageous because it can be quickly placed in orreprotected from rain.

down back of the seat and thus leave the board C exposed between theclips 2 and 8. By sliding the eyes or rings 13 downwardly along thestrips 1 and 7 and thence forwardly along the clips and finallydownwardly onto those portions of the clips under the board C, thecushion can be held suspended under the What is claimed is 4 v A seatback including oppositely disposed U-shaped clips, a cross stripintegral with the lower portion with said portions for engaging thelower surface of the structure to which the back is applied, connectedside strips extending board where it will be thereof and cooperating ionand slidable along the diverging side I strips and along the upper andlower portions of the clips, said cushion being adapted to swingrearwardly between the side strips. lln testimony that I claim theforegoing as my own, I have hereto afiixed my signature in the presenceof two witnesses.
